Let users use custom css files

[bubbl3]

I would like to give my users the possibility specify a custom css file so that they can customize my site look and feel. For now they are doing it with browser extensions, but it would be nice to add this option directly in their profiles.
Anyone as ever done this and/or has suggestions?

Oh well, I found a way to do it: http://xenforo.com/community/resources/enable-users-to-specify-a-custom-css-file.1043/
